Range Low 2: Selects the low end of the operating range for Zone 2. This parameter
determines the low end of the process input, set point and alarms. See the model
number and specification information on the inside back cover, and Table 1 below for
sensor range values. 0.0VDC, 0mA or 4mA represent Range Low (rL) for process
inputs and outputs. The process input is linearly scaled between rL and rH.
This parameter only appears if you have a dual zone control.
Range: Sensor range low to rH2 Default: Low limit of sensor type
Range High 2: Selects the high end of the operating range for Zone 2. This parameter
determines the high end of the process input, set point and alarms. 5.0VDC, 10.0VDC,
or 20mA represent Range High (rH2) for process inputs and outputs. The process input
is linearly scaled between rL and rH. This parameter only appears if you have a dual
zone control.
Range: Sensor range high to rL2 Default: High limit of sensor type
Hysteresis 2: Selects the switching hysteresis for Zone 2 when Pb2 = 0 (ON/OFF).
See Page 17 for the Pb2 parameter. This parameter only appears if you have a dual
zone control.
Range: 1 to 99°F/1 to 55°C/1 to 99 Units Default: 3°F
Alarm Type 2: Determines whether the alarm type for Zone 2 is process (Pr), deviation
(dE), or none (no). A process alarm is set at an absolute temperature. A deviation
alarm follows or tracks the set point. This parameter only appears if you have a dual
zone control and has alarms.
Range: Pr, dE, no Default: Pr
Alarm 2 Low: Represents the low process alarm or low deviation alarm for Zone 2.
This parameter only appears if you have a dual zone control, alarms, and AL2 no.
If AL2 = dE:
Range: 0 to -999°F/0 to -555°C/0 to -999 Units Default: -999°F
If AL2 = Pr:
Range: rL2 to A2HI Default: rL2
Alarm 2 High: Represents the high process alarm or high deviation alarm for Zone 2.
This parameter only appears if you have a dual zone control, alarms, and AL2 no.
If AL2 = dE:
Range: 0 to 999°F/0 to 555°C/0 to 999 Units Default: 999°F
If AL2 = Pr:
Range: A2LO to rH2 Default: rH2
Calibration Offset 2: Adds or subtracts degrees from the Zone 2 input signal. This
parameter only appears if you have a dual zone control.
Range: -99 to 99°F/-55 to 55°C/-99 to 99 Units Default: 0
